With temperatures on the rise, it’s time to shed the extra layers and bare it all — or at least those guns you’ve been working on all winter. As the recent runway shows of Versace, Dior, General Idea, and Kenneth Cole demonstrated nicely, sleeveless doesn’t have to mean an old cut-off tee reserved for hot, lazy weekends. Instead, opt for a dressy shirt that allows you to beat the heat and still look sharp. You can pair it with slacks, jeans, or shorts, and, depending on your sense of adventure, even go for something a little flashy. Just save the mesh for the gym.
